Welding

The weldability of Sandvik 6LR62 is good. Welding must be carried out without preheating and subsequent heat treatment is normally not required. Suitable methods of fusion welding are manual metal-arc welding (MMA/SMAW) and gas-shielded arc welding, with the TIG/GTAW method as first choice.

For Sandvik 6LR62, heat input of <2.0 kJ/mm and interpass temperature of <150°C (300°F) are recommended.
